Algeta to evaluate novel Targeted Thorium Conjugate (TTC) based on Avipep's Avibody platform

Algeta to evaluate novel Targeted Thorium Conjugate (TTC) based on Avipep's 
Avibody platform 
OSLO, NORWAY -- (Marketwired) -- 06/11/13 -- Algeta ASA (OSE: ALGETA)
announces a collaboration
with Australian biotechnology company
Avipep Pty Ltd to evaluate a novel Targeted Thorium Conjugate (TTC)
based on combining Algeta's proprietary thorium-227
alpha-pharmaceutical payload with an Avibody(TM) from Avipep
targets a number of different solid tumor types. 
Under the terms of the agreement, Avipep will provide access to a
Avibody, a next-generation antibody fragment, and Algeta
will provide access to chelation and conjugation technologies, as
well as to its alpha particle-emitting payload thorium-227. Both
companies will contribute financially to the collaboration, which is
expected to last for up to one year initially with the
option for
further cooperation thereafter. No further terms have been disclosed. 
Thomas Ramdahl, Executive Vice President and Chief Technology Officer
at Algeta,
said:  "This TTC  evaluation agreement  is a  further step 
towards our goal of building an attractive pipeline of thorium-based
alpha pharmaceuticals. Avivep's
Avibody  has shown excellent tumor
localizing properties in model systems and we hope  that when armed
with our  highly potent thorium-227 payload this novel TTC will offer
maximum therapeutic benefit." 
About the Algeta TTC Platform 
Algeta is evaluating the potential utility of alpha-particle emitting
in the treatment of cancer. Previous studies[i] have
indicated that such elements may have value in treating cancers by
causing double-strand DNA breaks
that trigger cell death, and have
also shown that the effects of alpha-emission are highly localized as
a result of the very short range of the alpha particle (2-10 cell
diameters), potentially minimizing off-target effects. Thorium-227 is
one alpha-particle emitting element (radionuclide) that has been
selected by Algeta for further investigation. By linking thorium-227
to cancer-targeting molecules such as monoclonal antibodies, Algeta
believes it may be possible to develop a pipeline of targeted
alpha-pharmaceuticals, termed Targeted Thorium
Conjugates, or TTCs.
Algeta intends to evaluate TTCs in a broad range of cancer
types to
determine whether the TTC platform could offer advantages over
(un-armed) antibodies or antibody-drug conjugate technologies
that use cytotoxic
drugs (rather than alpha-emitting elements) as
payloads. Such advantages may
include increased potency, a more
localized tumoricidal effect and the potential
to address drug
resistance by virtue of the physical action of the alpha particles.

Algeta  is a company focused on developing novel targeted therapies
for patients
with   cancer  based  on  its  alpha-pharmaceutical 
platform.  The Company  is headquartered in Oslo, Norway, and has a

About Avipep Pty Ltd 
Avipep  is  a  privately  owned  biotechnology  company  developing
ADCs for the treatment  of cancer.  Avipep's proprietary  Avibody(TM)
products are engineered
antibody  related  proteins  that  can 
deliver  either  cancer-killing drugs or cancer-imaging  agents 
directly  and  specifically  to  tumours. Antibodies are natural 
proteins in the  body's immune system  that can target  cancer cells
by binding  to specific molecules on  the cancer-cell surface.
Avibody(TM) products
leverage the targeting capacity of natural
antibodies but are tuned for improved
tumour targeting and in-vivo
performance. To date the Company has generated pre-clinical  animal
results that  suggest the exciting  potential for the approach.
